The Pentax DA 40mm f2.8 Limited lens tested had a serial number of 0007921, while the DA 70mm f2.4 Limited had a serial number of 0003685. We tested each lens using a Pentax K10D running the latest firmware version 1.1 released on January 23 2007. Following our convention of using default factory and best quality JPEG settings to test camera bodies unless otherwise stated, the K10D was set to JPEG 10M *** mode and sRGB colour space, with Auto White Balance, Multi Segment metering, Natural Image Tone, and Sharpness, Contrast and Saturation set to their zero positions.
